Isolated upper buttock pain provoked by L5 nerve root compression - a case report.

Unlabelled: Nerve root compression in lumbar spine may be associated with low back pain. However, isolated gluteal pain without any radicular symptoms in patient with lateral recess stenosis is rather unexpected and to our knowledge was not reported in the literature.

A Case Report: We present a patient that suffered from isolated upper buttock pain without any radicular component.

Intra-operative fluorescein videoangiography-related nephrotoxicity in intracranial aneurysm surgery: Single center, observational cohort study.

Objectives: Intra-operative fluorescein video angiography (FL-VA) has been given increasing attention recently and several studies reported its high utility in neurovascular surgery. The aim of this study was to evaluate the safety of FL-VA in a prospective, single-center cohort of patients operated due to cerebral aneurysms.

Patients And Methods: This is an observational cohort study including 150 patients operated due to intracranial aneurysms.

Predictors of Intraoperative Aneurysm Rupture, Aneurysm Remnant, and Brain Ischemia following Microsurgical Clipping of Intracranial Aneurysms: Single-Center, Retrospective Cohort Study.

Background And Study Aims:  Complete microsurgical clip occlusion of an aneurysm is one of the most important challenges in cerebrovascular surgery. Incorrect position of clip blades as well as intraoperative aneurysm rupture can expose the patient to serious complications such as rebleeding in case of aneurysm remnant and cerebral ischemia in case of occlusion of branching arteries or perforators. The aim of this study was to identify independent predictors of surgery-derived complications (aneurysm remnant and brain ischemia) as well as intraoperative aneurysm rupture in an institutional series of patients.

Superior Hypophyseal Artery Ruptured Aneurysm in a 5-Month-Old Child Presenting as an Acute Subdural Hematoma: A Case Report.

Introduction: We present a very rare case of ruptured superior hypophyseal artery (SHA) aneurysm that presented as an acute subdural hematoma (SDH) discussing its initial presentation, diagnosis, and treatment modalities. To our knowledge it is one of very few if any cases of a ruptured aneurysm in infants regarding that specific vascular location.

Case Report: A 5-month-old boy was referred to our department due to acute SDH over the right cerebral hemisphere without significant mass effect nor hydrocephalus.

Predicting conservative treatment failure in patients with lumbar disc herniation. Single center, case-control study.

Objectives: The aim of this study was to identify independent predictors of conservative treatment failure in patients presenting due to lumbar disc herniation-associated low back pain and sciatica.

Patients And Methods: This is a single institution, case-control study including 240 patients that were selected for microsurgical or conservative treatment due to lumbar disc herniation in a 2,5-year period. Bivariate and multivariate analyses were performed in order to identify independent predictors among demographic, clinical and radiographic factors.

Intraoperative fluorescein video angiography in intracranial aneurysm surgery: single-center, observational cohort study.

The aim of this study was to compare the incidence of postoperative, surgery-related complications in patients where fluorescein video angiography (FL-VA) was performed with those operated without intraoperative verification. This is an observational cohort study including 97 patients who were selected for microsurgical clipping due to intracranial aneurysm. First 52 patients enrolled in the study were operated prior to introduction of fluorescein fluorescence in our surgical workflow.

Factors determining the best surgical exposure and safe clip positioning in surgical treatment of anterior communicating artery (AComA) aneurysms - particular significance of AComA complex rotation in the axial plane.

Introduction: The aim of this study was to evaluate whether Anterior Communicating Artery (AComA) complex rotation in axial plane may influence the ease of surgical exploration in this region and safety of clip positioning when left vs right-sided approach is compared.

Materials And Methods: This is a retrospective study based on analysis of patients operated due to AComA aneurysm, both ruptured and unruptured. AComA complex position in relation to coronal plane was evaluated using 3D-CTA VR reconstructions.

Intraoperative fluorescein videoangiography in cerebral aneurysm surgery - a preliminary study.

Unlabelled: One of the most important challenges in intracranial aneurysm surgery is safe and correct clip deployment. Various methods have been developed in order to improve surgeon's intraoperative confidence and provide real-time information about the efficacy of clipping. Sodium fluorescein video angiography, however, was not well studied so far.

Spine surgery under general anaesthesia complicated by Wernicke’s encephalopathy in previously asymptomatic patient.

Wernicke’s encephalopathy (WE) is a very rare complication of surgical intervention, especially among patients with no liver dysfunction and no history of alcohol abuse. In a surgical setting, Wernicke’s syndrome was mostly associated with abdominal surgery (bariatric, e.g.

Clinical application of 3D pre-bent titanium implants for orbital floor fractures.

Introduction: Orbital structures are affected in approximately 40% of all cases of craniofacial trauma. Changes in the bony orbital dimensions can alter the function of intraorbital contents and lead to serious complications. The unique anatomy of the orbit and the resulting surgical approaches make the process of fitting and aligning implants difficult, time consuming and operator dependent.

[Role of proteoglycans and glycosaminoglycans in the intervertebral disc degeneration].

Proteoglycans and glycosaminoglycans are the main components of the extracellular matrix of the nucleus pulposus. Intervertebral disc degeneration due to aging and excessive mechanical loads results in adverse quantitative and structural changes to the macromolecules. Metalloproteinases induced by inflammatory mediators play a key role in degrading proteoglycans.

[Supplementation of cranial defects by an autologous bone flap stored in the abdominal wall].

Background And Purpose: The aim of this paper is to present an alternative method of cranioplasty with the use of an autologous cranial bone flap stored between primary and restorative surgery in the subcutaneous pocket in the lateral hypogastric region.

Material And Methods: Between January 1999 and April 2002, in the Department of Neurosurgery of Medical University of Łódź we performed 36 procedures of the bone flap implantation into the abdominal subcutaneous fat tissue. These procedures followed craniectomy, mainly in cases of acute subdural hematomas and ruptured intracranial aneurysms.

[Intraoperative assessment of cognitive and executive functions in patients with brain tumors].

Background And Purpose: The aim of this paper was to evaluate the usefulness of selected methods of intraoperative neuropsychological assessment. In order to investigate the influence of the direct cortical stimulation and tumor resection on the patients' intraoperative performance, we examined selected areas of cerebral cortex involved in cognitive activity in patients undergoing awake craniotomy for brain tumors.

Material And Methods: The analyzed group consisted of 21 patients (11 men, 10 women) with tumors located in eloquent areas of the left hemisphere.

[Awake craniotomy and brain mapping for eloquent cortex in patients with supratentorial tumors: a preliminary report].

Malignant brain tumours are incurable at present. Since none of the hitherto used treatment methods allows to significantly extend these patients' survival time, the basic aim is to improve their quality of life. Intraoperative brain mapping seems to be an approach enabling to minimize the risk of irreversible damages to functionally important structures of the brain.
